mtlb_tril

Description

With complex input: Matlab tril can be used with complex data but not Scilab one.

With character strings inputs: due to the fact the Matlab and Scilab do not consider character
strings in the same way, Scilab and Matlab tril do not give the same results
for this type of input.

With boolean inputs: Matlab tril can be used with boobean data but not Scilab one.

The function mtlb_tril(x,k) is used by
mfile2sci to replace tril(x,k) when it was not
possible to know what were the inputs while porting Matlab code to Scilab. This function will
determine the correct semantic at run time. If you want to have a
more efficient code it is possible to replace mtlb_tril calls:

If X contains real double values
mtlb_tril(x,k) may be replaced by tril(x,k)

If X contains boolean values
mtlb_tril(x,k) may be replaced by tril(bool2s(x),k)
